Tongueforge is a spaced-repetition app for people learning properly: typed recall, reading passages, scripted conversations, listening practice, and a smart scheduler that knows exactly when you need to see each word again. No game-layer noise, no guilt.
Tongueforge is designed for adult learners reactivating dormant skills or building real production ability, not casual tap-through practice.
FSRS-6 spaced repetition brings each word back at exactly the moment you need to see it again — and in Advanced Mode, it can tune itself to your personal memory from your own review history.
Fewer reviews. Stronger recall.Vocabulary, conjugation, cloze grammar, reading passages, dialogues, and graded reader stories — curated per language and gated to your CEFR level, from A0 to B2.
Start where you are, never drown in the wrong material.Built with SwiftUI, local-first with private iCloud sync, home-screen widgets, and no ads or third-party tracking.
Your learning data stays yours, even offline.The daily loop, end to end: see what's ready, review by typing and getting corrected, and read progress that actually means something.
Today — what's ready, at a glance
Review — type it, get corrected
Progress — readable, honest signal
Bjork's idea is simple: if practice feels too easy, it usually is. Tongueforge turns that into a daily review system with better timing, harder recall, real context, and tutor-like correction — delivered with warmth, never guilt.
